CUTTINGLDIE.

Be it known that I, .Annul-Nuno DE'wEs, a

'citizen of the United States, and a resident of Brooklyn, county lof Kings, State of New York, have invented new and useful Improvements in Cutting-Dies, of which the following 1s a specltlcation.

--forced 'through said beddown onto 'the' This invention relates to that class -of cutting dies-having cutting edges shaped to conform to the cutsto 'be made which are driven, chisel fashion, through vthe material,

such as paper, leather.- '&c.

'lhelnvention involves an improvement in the art of making such dles, and consists 1u `securing to a metal plate, constituting :t resisting base, 'a plate of a tenacious tough material, asclose orrain wood, to constitute'ahold'- ing bed for. tzlie knives or cutters, then forming slits through the cutter holding bed to coliform to the design of the cuts to be made by means of thin tools or drifts which are metal base,then placing in the slit strips of suitable cutting metal of a. thicknessV rto snugly fit the slits and of a' width to seat on the supporting base and extend outwardly beyond the exposed surface ofthe cutter liold ing gbed, said outer edges of the strips being beveled or sharpened to constitute the'cntting edges of the die.' ';l`o provide means for discharging from the die all of the parts of thc. sheetor sheets of paper or other material after being acted upon by the .die it is contemplated to fill all of the spaces between and surrounding the parts of the sides'of the Vcutters extending beyond the cutter holdingr bed with an elastic material, and this is accomplished by placing a sheet of such material, as india rubber, in contact with the cutting' edges of the cutters and forcing it down over the cutters to cause them to fully penetrate it, said elastic material being of such a thickness as to extend to or be slightlyv above V'the cutting edges and completely fill the spaces between the cutters. To insurethat all parts -of the cutter holding bed are retained in proper position, particularly parts entirely surrounded by slits, it is proposed to Y attach, by a suitable oement,'to the under ered side of the bed ay sheet of fibrous material, as canvas, which will be in Contact with the metal base, but will not necessarily be sevthe slit making tools, which, while aracter to sever thecutter holding be.d,are not sharp enough to cutthe canvas. -to be cut or made inor through the articles The accompanying drawings 'to which I will now refer illustratea cutting die made according to this invention.

Figure `1 is a plan view,'sectionally broken away,sho\'\;ing theconstituent parts of a.

cutting die made under this'inven'tion andv the manner o f their asseu'iblage. Fig. 2. is a transverse section of the same, taken on, the line 2, 2, Fig. 1. Fig. 3 shows, sectionally, a portion of the cutting' die and a tool for making the slits in the cutter holding bed, and Fig. represents an article, as an 'advertising sign.. the "la'odnct of a cutting process of the die illustrated.

Cutting dies made in -accordam'e with this invention are, as will be .seen from the dra wings, comparatively shallow and cost much less to make than cutting dies of ordinary construction. The base plate @consists of a, metal sutli'ciently resistant to support the cutting blades, whichscat edgewise thereon, so that theirV cutting edges will be. maintained in a level or proper cutting plane. The cutter bed .L in which the cutters are held isa plate of uniform thickness of a,

tenacious tough material adapted to have l slots formed through it without fracturinfr, a close `rained wood being found a sntab e material. This plate b is preferablyreinforced by a suitable fabric 'c securely attached, by glue or cement, to its under side; this fabric prevent-s displacement of partsof the cutter bed Vwhile/the vslits are being made, particularly those parts that. are entirely surrounded by slits. In some cases it may of course beV nimecessary to use the jreinforcing fabric c. The bed I) is securely fastened to the base plate f1/hy screws c located at suitable points, the reinforcing fabric c, when'used, being adjacent to the base plate. The bed may be secured to the base plate a bycement; in any case some marked orindicated the lines of the design driven down through the bed b onto thebase plate a so as to sever or separate'its mass ethus making narrow slits, as shown at "IL,

"f, To'provide- -means'for discharging; or striping thesheet or sheets cut by the cutters d rom the die a sheet f of requisitelexibility is placed on the cutters and forced on to them so as to be fully penetrated by them,

said flexible material belng seated in contact with the upper face 'offthe bed b, and thenv flli n Vall spaces'between .and surrounding the sides of the arts of the cutters extending above the be '6, the thickness of'fthema-y der, side, before bein place terial f being such asV to preferably. extend slightly :`beyond' the plane., of the -cutting edges ofthe cutters d.
